Have an 84 Somerset with Waterbouy windows. (Radius corners) Untill this year, none of them have ever leaked, untill this year that is !!!!! Had about a 4" rain over 2 days and had one window leak. It is leaking on the inside of the window, at the top where the _frame_ comes together. I have looked at the outside and can find no source of where water could be coming in at. Anybody had the same problem. Ruined the drapes with that dreaded brown water stain. Help!!!
